Experienced operators know that the bucket is the most widely used working device in excavator operations and the part that bears the greatest load during excavation. In other words, reinforcing the bucket is crucial for the normal operation of the excavator. Today, I will share how to reinforce an excavator bucket.

Data shows that an excavator needs 4-5 buckets on average every 8 years, especially in stone construction environments where buckets wear out faster. Therefore, the excavator's bucket is considered a consumable part. When the bucket wears out to a certain extent, it should be reinforced in time to effectively extend its service life.

During the bucket reinforcement process, most people have this misconception: just randomly welding a bunch of steel plates is enough. In fact, such blind reinforcement of the bucket does more harm than good to the excavator. It's essential to master scientific reinforcement methods, which I'll explain one by one.

Reinforcing an Excavator Bucket Needs Caution - Avoid Blind Operations

The manufacturing technology of excavators has been developing for over a hundred years, and the technology of buckets is also very mature. For instance, every Doosan bucket perfectly applies the principles of stress analysis. Without excessive wear, welding reinforcement plates over a large area can disrupt the stress balance of the bucket, increasing excavation resistance and sometimes even accelerating wear and tear.

If the bucket is fully protected, it will increase its weight. A heavier bucket not only increases fuel consumption but also significantly impacts the equipment's lifespan under high-load operations. Therefore, if there is significant wear, targeted reinforcement should be carried out on specific areas, not indiscriminate reinforcement.

Key Points to Note in Excavator Bucket Reinforcement

1. 1. Welding should be done by skilled technicians to ensure strong and effective joints.

2. 2. Perform partial welding in areas that require the most reinforcement, instead of overall welding, to avoid reducing the efficiency of the excavator and increasing fuel consumption.

Experience in Reinforcing Excavator Buckets

1. 1. Regularly observe the wear level of the bucket's edge blades, bottom plate, side plates, and tooth roots, and reinforce these areas as necessary.

2. 2. Reinforcing the tooth root mounting plate is essential. This can be done by adding reinforcing bars or covering with wear-resistant blocks.

3. 3. Installing edge blades on the side plates can protect them and reduce wear.

4. 4. Strengthening the bottom plate is also crucial. The reinforcing bars for the bottom plate should be made of hard, wear-resistant, long flat materials. It's important to maintain the bucket's overall shape to avoid affecting the cutting angle and productivity.

Maintain Good Operating Habits

Proper operating habits can not only improve work efficiency but also reduce the wear rate of the bucket, thereby protecting it.
